Question 1

It is recommended that UTP cables be secured no more than __________ inches from an enclosure.

Accepted Answer

It is recommended that UTP (Unshielded Twisted Pair) cables be secured no more than 12 inches from an enclosure to ensure proper cable management and reduce the risk of damage or interference.

Question 2

When installing voice, video and data wiring in a house, Articles __________ and __________ of the NEC contain some requirements that must be followed.

Accepted Answer

Articles 800 and 820 of the National Electrical Code (NEC) cover requirements for communications circuits and community antenna television and radio distribution systems, respectively, which are relevant to voice, video, and data wiring installations.

Question 3

The letters CMR found on a UTP cable is an abbreviation for __________.

Accepted Answer

CMR stands for Communications Riser Cable, which is a type of cable specifically designed for vertical installations between floors in a building.

Question 4

A __________ is the hub of a structured wiring system and is usually located in the basement or garage. It is sometimes called a 'distribution center'.

Accepted Answer

A service center acts as the central point in a structured wiring system, distributing various services throughout a building from a common location, often found in basements or garages.

Question 5

The popular name given to an eight-pin connector or jack used to terminate UTP cable is __________.

Accepted Answer

The RJ-45 connector is commonly used to terminate UTP (Unshielded Twisted Pair) cable, which is used for Ethernet networking. It has eight pins arranged in a specific pattern and is compatible with Category 5 (Cat5) and Category 6 (Cat6) cables.

Question 6

_______ ensures that basic continuity and correct terminations have been applied, but does not attempt to measure the information-carrying capacity of the cable runs like you would do in a commercial installation

Accepted Answer

Verification ensures that basic continuity and correct terminations have been applied, but does not attempt to measure the information-carrying capacity of the cable runs like you would do in a commercial installation. Certification (option A) involves more comprehensive cable testing and measurement of information-carrying capacity. Inspection (option C) typically refers to examining the physical condition of the cable and its installation, rather than testing for continuity or information-carrying capacity. Attenuation (option D) refers to the loss of signal strength over a cable, and is not directly related to cable testing or verification.

Question 7

Coaxial cable must be separated from electric light and power circuits by at least __________ inches. (General Rule)

Accepted Answer

The answer of Coaxial cable must be separated from electric...

Question 8

Which of the following is not a recommended installation method for structured wiring cables?

Accepted Answer

There should not be any splices.

Question 9

____________________ identifies the amount of data that can be sent on a given cable and is measured in Hertz.

Accepted Answer

The answer of ____________________ identifies the amount of data that...

Question 10

The color coding for a 4-pair UTP cable can be remembered by using the acronym 'BLOGB'. Using this as a reminder, the colors used for pair #3 is __________ and __________.

Accepted Answer

The answer of The color coding for a 4-pair UTP...

Question 11

When installing voice, video and data jacks throughout a house, the preferred piece of equipment used to mount the jacks in a wall is a __________.

Accepted Answer

Mud rings, also known as plaster rings, are preferred for mounting voice, video, and data jacks in walls because they provide a stable, flush surface for the installation without the need for a full enclosure, allowing for easier cable management and access.

Question 12

The maximum length for UTP and STP cables installed in houses is ________ feet.

Accepted Answer

The maximum length for UTP (Unshielded Twisted Pair) and STP (Shielded Twisted Pair) cables in Ethernet networks is 100 meters, which is approximately 328 feet. This limit is set to ensure data integrity and network performance.

Question 13

The decrease in the power of a signal as it passes through a cable, which is measured in decibels is _________.

Accepted Answer

Attenuation is the decrease in power of a signal as it passes through a cable, measured in decibels. Exaggeration is not a term used to describe the decrease in signal power. Bandwidth refers to the range of frequencies a cable or device can handle. Megahertz refers to the frequency of a signal, not the decrease in signal power.

Question 14

________ refers to the process of making measurements and then comparing the results obtained to pre-defined standards, so that a pass/fail determination can be made.

Accepted Answer

The answer of ________ refers to the process of making...

Question 15

Coaxial cable limited to use in dwelling units or raceways is labeled __________.

Accepted Answer

CATVX is the designation for coaxial cables that are limited to use in dwelling units or raceways.

Question 16

The rating on the bandwidth performance of UTP cable is called the ____________________ and includes 3, 4, 5, 5e, 6, and 6a.

Accepted Answer

The answer of The rating on the bandwidth performance of...

Question 17

It is a good idea to use 75-ohm F-Type __________ in each unused television outlet and at each unused splitter port throughout a house.

Accepted Answer

It is recommended to use termination caps to prevent signal loss and interference in unused television outlets and splitter ports throughout a house. Dust caps and plugs may not provide adequate protection against signal degradation. Jacks are used for connecting cables to outlets and devices, not for terminating unused ports.

Question 18

It is recommended that UTP cable be bent so that the radius of the bend is not less than __________ times the diameter of the cable.

Accepted Answer

The recommended minimum bend radius for UTP cable is typically 4 times the diameter of the cable to prevent damage and maintain performance.

Question 19

A(n) __________ terminates voice, video and data wires to a punch-down block.

Accepted Answer

The answer of A(n) __________ terminates voice, video and data...

Question 20

When running voice, video or data cables along joists in a basement, it is a good idea to use __________ instead of staples.

Accepted Answer

J-hooks are the best choice for running cables along joists in a basement. Staples can damage the cable by crimping or cutting into it, while J-hooks provide support without causing damage. Additionally, J-hooks can easily accommodate multiple cables, which is often necessary when running voice, video or data cables.
